TC7129  
4-1/2 Digit Analog-to-Digital Converters with  
On-Chip LCD Drivers  
Features  
General Description  
• Count Resolution: ±19,999  
The TC7129 is a 4-1/2 digit analog-to-digital converter  
(ADC) that directly drives a multiplexed liquid crystal  
display (LCD). Fabricated in high performance, low  
power CMOS, the TC7129 ADC is designed specifi-  
cally for high resolution, battery powered digital multi-  
meter applications. The traditional dual slope method  
of A/D conversion has been enhanced with a succes-  
sive integration technique to produce readings accu-  
rate to better than 0.005% of full scale, and resolution  
down to 10µV per count.  
• Resolution on 200mV Scale: 10µV  
• True Differential Input and Reference  
• Low Power Consumption: 500µA at 9V  
• Direct LCD Driver for 4-1/2 Digits, Decimal Points,  
Low Battery Indicator, and Continuity Indicator  
• Over Range and Under Range Outputs  
• Range Select Input: 10:1  
• High Common Mode Rejection Ratio: 110dB  
• External Phase Compensation Not Required  
The TC7129 includes features important to multimeter  
applications. It detects and indicates low battery condi-  
tion. A continuity output drives an annunciator on the  
display, and can be used with an external driver to  
sound an audible alarm. Over range and under range  
outputs and a range change input provide the ability to  
create auto-ranging instruments. For snapshot read-  
ings, the TC7129 includes a latch-and-hold input to  
freeze the present reading. This combination of features  
makes the TC7129 the ideal choice for full featured  
multimeter and digital measurement applications.
